What are the four steps for solving a problem? Should any other factors be accounted for when solving a problem? Should any factors be accounted for when explaining how to solve a problem?

Answers

Analysis of the problem - working out what the problem is and setting down any testing that will happen to check that the solution works.

Design the solution - maybe there is more than one way to solve the problem, but the best way needs to be designed

Implementation of the design - produce the design: testing that the solution works should be included here

Evaluation - The solution is now used to solve the problem: Feedback is asked for to check that the solution does meet the original problem and solves it.

Can any one help me with this question

Answers

The answer to your question is: Yes.

Now, would you like to actually see the solution ?

First, multiply the quantity out:

(sin + cos)² = sin²(t) + cos²(t) + 2sin(t)cos(t)

You need to know:
==> sin²(any angle) + cos²(the same angle) = 1
==> 2sin(any angle)cos(the same angle) = sin(double the angle)

So the equation becomes:

(sin + cos)² = 1 + sin(2t)

$(sin\ t+cos\ t)^2=sin^2t+cos^2t+2\cdot sin\ t\cdot cos\ t=1+sin\ 2t$

Allegra has a cell-phone plan that charges $65 per month and $0.10 for every minute that she uses the phone beyond what her plan allows. One month, she was billed $73.40.a. Define a variable for the unknown.
b. Write an equation to model the problem. Explain your answer.
c. Solve the equation. Show your work.
d. Find the number of minutes that Allegra went over the time that the plan allows. Explain your answer.

Please help me with this problem, I don’t understand it. Thanks in advance! :D

Answers

It seems confusing, but it's just breaking down the steps for you. It's done the same as any other word problem.
a. The unknown is how many minutes she used beyond the plan. So, we'll use "m" for the variable, to represent minutes.
b. 73.40 = 65 + 0.10m
   The 73.40 is the total, which is why it's by itself. 65 represents the price per month for the plan, and 0.10m is the price per extra minute multiplied by the unknown amount of minutes used.
c. 73.40 = 65 + 0.10m
   8.40 = 0.10m
   84 = m
d. The number of minutes that Allegra went over the time that the plan allows is found by solving the equation we just wrote and solved. $0.10 is paid for every minute past the plan's allowance, meaning that "m" in the equation, when solved, shows us exactly how many minutes over Allegra went.

Answer:

Step-by-step explanation:

a(n) = n² - 3n - a(n-1) and a(1) = 4

We have a(1) = 4 and want a(2) (for which n = 2).

a(2) = 2² - 3(2) - a(2-1) → a(2) = 4 - 6 - 4 = -6 = a(2)

a(3) = 3² - 3(3) - (-6) = 9 - 9 + 6 = 6 = a(3)

a(4) = 4² - 3(4) - 6 = 16 - 12 - 6 = -2 = a(4)

a(5) = 5² - 3(5) + 2 = 12 = a(5)

Which linear inequality is represented by the graph?

Answers

Linear inequality represented by the graph is

$\displaystyle y\leq (1)/(3)x-4$

Further explanation

Straight-line equations are mathematical equations that are described in the plane of cartesian coordinates

General formula

$\large{\boxed{\bold{y-y1=m(x-x1)}}$

y = mx + c

Where

m = straight-line gradient which is the slope of the line

x1, y1 = the Cartesian coordinate that is crossed by the line

c = constant

The formula for a gradient (m) between 2 points

$\large{\boxed{\bold{m= (y2-y1)/(x2-x1)}}$

If the intersection of the x-axis (b, 0) and the y-axis (0, a) then the equation of the line:

ax + by = ab

It says inequality if there are symbol forms like <,>,≤ or ≥

Whereas linear inequality can have forms: ax + by> cax + by ≥ cax + by <cax + by ≤ c

In graphical form, line inequality can be

dashed line because y does not include equals to
a solid line because y includes equal to

For line inequality (positive coefficient y)

ax + by ≥ c then the solution is shaded upwards

ax + by ≤ c then the solution is shaded down

Or we input the values x, y from the point in the shaded area and put in the inequality line

From the picture we can determine the equation of the line

Line through 2 points (0, -4) and (-3, -5)

the gradient: $\displaystyle =(-5+4)/(-3-0)\n\n=(1)/(3)$

the equation of the line:

$\displaystyle y-y1=m(x-x1)\n\ny+4=(1)/(3)(x-0)\n\n=(1)/(3)x-4$

We check the point in the area of shading, for example (0, -6)

we input in the equation :

$\displaystyle -6=(1)/(3).0-4\n\n-6=-4$

Because -6 < -4 and the graph is solid line so the inequality line will be

$\displaystyle y\leq (1)/(3)x-4$

In the given graph the line is having the y intercept as -4.

The slope of line = $(Rise)/(Run) =(1)/(3)$

The equation of the line is $y=(1)/(3)x-4$

The line is a dark line so inequality will be either ≤ or ≥.

Consider point (0,-5)which lie in the shaded region.

Plug x=0 and y=0 in the equation of line,

-5= $(1)/(3)(0)-4=-4$

-5≤ -4 .

The inequality equation for the given graph is

y≤ $(1)/(3)x-4$
